CRUSTACEA OF NORTHUMBERLAND AND DURHAM 



Fam. 2o.— AORIDiE 



MiCRODEUTOPUS ANOMALus (Rathkc). 



I have the following notes; seven miles off Tynemouth, 25 

 fathoms, frequent : off Holy Island, 1864 (A. M. N.); Sunder- 

 land, low water (G. S. B.); but the only specimens now in my 

 collection are those from off Holy Island, which prove to be 

 females of Protomedeia fasciafa (which see). This throws 

 some doubt on the other records. Females of the Aoridae 

 are often, especially young, difficult to distinguish ; but the 

 species last named is not likely to have occurred at low 

 water. Mr, Meek in his list gives " Microdeutopns sp., a 

 female was obtained at Cambois Bay in August, 1901."

Fam. 21.— PHOTIDyE 



Protomedeia fasciata Kroyer. 



Off Alnmouth, 39-50 fathoms, and 16 miles off Souter 

 Point, 39 fathoms (A. Mk.). These specimens found by Mr. 

 Meek were very young; on re-examining three specimens which 

 were recorded in 1865 as ^' Microdeutopus anomalus" from off 

 Holy Island, 38-50 fathoms, I find them to be full grown 

 {^\\\d\&% oi Protomedeia fasciata. A character which was the 

 first to catch my eye, and is a very distinctive one, was the 

 very slender propodos of the anterior pairs of peraeopoda, and 

 the slenderness and great lengtli of the nail, which is quite as
